I/O Wiring

To access I/O Wiring
From the
Application View
, right-click a device, and then click
I/O Wiring
.
Configure settings in
I/O Wiring
 to connect project variables to channels of I/O boards or complex equipment existing on a target system. To set up I/O wiring, add I/O devices to a rack and then wire variables to the I/O channels of the devices.
An I/O device represents an I/O board or complex equipment on a rack list. Individual I/O boards and single pieces of equipment can have up to 128 I/O channels. An I/O device has channels with the same data type and direction.
I/O channels represent hardware input or output points. Connect an I/O variable to a channel for use in program organization units (POUs). I/O variable values can be locked, unlocked, and forced as needed during program debugging.
The
I/O Wiring
 view has two sections:
  • A rack list, displays defined complex equipment and I/O boards in the slots. An order number identifies each slot. Expanding the equipment accesses information and single devices.
  • A channel variables list, enables the association of channels with variables. This list displays the name of all variables. When online, the channel variables list also displays the logical value, physical value, and lock status of all variables.
Apply conversion tables to analog input or output variables to create proportional relationships between electrical values (read on input sensor or sent to the output device) and physical values used in application programming.
The following product families of I/O boards and complex equipment are available for use in a project. Simulation does not support some I/O boards and complex equipment.
TIP:
  • To simulate I/O boards and complex equipment not supported for simulation, toggle the I/O device to the virtual attribute.
  • If you change the variable wiring, the variable will be removed from the SOE collection.
